The Team GP Undertaker V2 models in this collection are built for high-output systems and are listed at 5,000 watts RMS. A subwoofer at this power level needs much more than a large amplifier.

Team GP Undertaker V2 Subwoofers

The Team GP Undertaker series is GP Car Audio's high-power subwoofer lineup for customers building systems around serious bass output.

Available Undertaker V2 sizes in this collection include:

  • Team GP Undertaker V2 12-inch subwoofer
  • Team GP Undertaker V2 15-inch subwoofer
  • Team GP Undertaker V2 18-inch subwoofer

Choosing between a 12, 15 or 18 should not be based only on which subwoofer is physically larger. The correct choice depends on available enclosure space, desired cone area, amplifier power, electrical support and what you want the finished system to do.

GP 12 Inch Subwoofer

The Team GP Undertaker V2 12-inch subwoofer is the most compact option in this Undertaker lineup and can be a strong choice for builders who want high power capability without the enclosure size required by a 15-inch or 18-inch subwoofer.

A high-power GP 12 can make sense for:

  • Single 12-inch high-output systems
  • Dual 12-inch bass builds
  • Trunk systems with limited enclosure space
  • SUV and hatchback installations
  • Loud daily-driver systems
  • Demo-style car audio builds

Do not assume every 12-inch enclosure will work simply because the subwoofer fits through the mounting hole. Airspace, mounting depth, port area, tuning frequency and subwoofer displacement all matter.

GP 15 Inch Subwoofer

The Team GP Undertaker V2 15-inch subwoofer gives builders more cone area than a comparable 12-inch driver while remaining practical for many large trunk, hatchback and SUV systems.

A 15-inch subwoofer can be a good choice for customers building around:

  • Deep daily-driver bass
  • Single high-power 15-inch systems
  • Dual 15-inch subwoofer builds
  • Large ported enclosures
  • SUV and hatchback systems
  • Demo and competition-style car audio builds

The extra cone area can provide greater displacement potential, but only when the enclosure and amplifier are properly matched to the subwoofer.

GP 18 Inch Subwoofer

The Team GP Undertaker V2 18-inch subwoofer is the largest Undertaker model currently in this collection and is intended for systems where enclosure space and cone area are major parts of the build plan.

An 18-inch car audio subwoofer can be a strong choice for:

  • Large SUV systems
  • Wall builds
  • Single 18-inch high-output systems
  • Dual 18-inch subwoofer systems
  • Demo vehicles
  • Competition-oriented bass systems
  • Customers looking for substantial cone area and air movement

An 18-inch subwoofer requires considerable enclosure space. Make sure the vehicle has enough usable room for the enclosure before choosing the subwoofer.

5,000 Watt RMS Team GP Subwoofers

The Undertaker V2 products in this collection are listed at 5,000 watts RMS, placing them firmly in the high-power car audio category.

A 5,000 watt RMS subwoofer does not mean you should simply connect any amplifier advertised as 5,000 watts and expect the system to work correctly.

The amplifier must be considered along with:

  • Subwoofer voice-coil configuration
  • Final wired impedance
  • Amplifier RMS output at that impedance
  • Enclosure design and tuning
  • Power and ground wire size
  • Battery reserve
  • Alternator output
  • Voltage stability
  • System tuning and clipping prevention

If you still need an amplifier, browse our monoblock car audio amplifiers for subwoofer systems.

Choosing a Subwoofer Box for a GP Undertaker

The enclosure is one of the most important parts of a high-power subwoofer system.

A strong subwoofer in the wrong box can perform poorly even when the amplifier and electrical system are capable. The enclosure affects how the woofer loads, how much airspace it has, the frequency range it favors and how efficiently the finished system uses the available power.

Before ordering a subwoofer box, compare:

  • Recommended net enclosure volume
  • Subwoofer displacement
  • Mounting diameter
  • Mounting depth
  • Port area
  • Port tuning
  • Number of subwoofers
  • Available vehicle space

Single vs Dual Team GP Undertaker Subs

A single Undertaker can already require a substantial amplifier and electrical system. Moving to two subwoofers increases cone area and potential output, but it also increases enclosure size, amplifier demand and electrical requirements.

Before building a dual-subwoofer setup, confirm the voice-coil configuration and resulting final impedance. The amplifier must be stable at the final load created by both subwoofers.

Do not choose the number of subs first and try to make the rest of the vehicle support them afterward. Plan the subwoofer count, enclosure, amplifier and electrical system together.

Power Wire & Electrical Support for High-Power Subs

A high-power Team GP bass system needs a strong electrical foundation.

Depending on the amplifier and total system demand, your build may require larger OFC power wire, upgraded grounds, additional battery capacity, a Big 3 upgrade and a high-output alternator.

Factory vehicle wiring and charging systems were not designed around multi-thousand-watt aftermarket amplifiers.
